Assessment

Most consistent: H1 (Managed De-escalation) -- The weight of evidence supports both sides wanting to reduce immediate war risk without making the substantive concessions required for a deal.

Cannot rule out: H2 and H4 -- Iran's simultaneous reconstruction efforts and the Gulf States' decisive role in saving the talks from collapse are both well-evidenced.

Least consistent: H5 (Genuine Deal) -- The narrow scope, indirect format, agenda disputes, immediate sanctions, and regime change planning all argue against genuine commitment to a comprehensive agreement at this stage.
